Rotten corners of the mouth may also be caused by some bad habits, such as liking to lick the corners of the mouth with your tongue or not liking drinking water very much. It is precisely because of these bad habits that a person's body lacks water, and the skin around his mouth is no exception. Once the skin around the mouth lacks moisture, it is inevitable that the mouth will rot.
Treatment of oral decay
There are some different remedies for how to treat rotten mouth corners in many places. But in general, some methods are universal. For example, we can eat more coarse grains and fresh fruits and vegetables. These foods are very high in cellulose, which can effectively help us replenish water and other nutrients. Therefore, it is of great help to treat rotten mouth corners.
Secondly, if you want to eradicate bad mouth, you must get rid of those bad living habits. For example, don't lick your mouth with your tongue all the time. It's neither elegant nor good for your mouth. It is better to do less. There is also the habit of drinking more water. Maybe we don't drink water when we are not thirsty, but many times even if we are not thirsty, it doesn't mean that we are not short of water, so we should add some water.
